5-(Benzotriazolyl)-substituted 3,4-dihydropyrid-2-ones were obtained by condensation of 4-benzo-triazolyl-5-phenyl(methyl)-5-oxopentanoic acids with benzyl or aryl amines. Dehydrogenation of 3,4-dihydropyrid-2-ones resulted in 5-benzotriazolyl-substituted pyrid-2-ones and/or 5-(phenylamino)pyrid-2-ones, products of nitrogen elimination from the benzotriazolyl substituent. In turn, 5-benzotriazol-1-yl-substituted
通过4-苯并三唑基-5-苯基(甲基)-5-氧戊酸与苄基或芳基胺的缩合反应,得到5-(苯并三唑基)-取代的3,4-二氢吡啶-2-酮。3,4-二氢吡啶-2-酮的脱氢得到5-苯并三唑基取代的吡啶-2-酮和/或5-(苯氨基)吡啶-2-酮,它们是从苯并三唑基取代基上除去氮的产物。反过来,5-苯并三唑-1-基取代的吡啶-2-酮在Graebe-Ullmann条件下消除了氮,得到吲哚并吡啶酮。
